5. What is the next generation Internet we needed Internet have been an important infrastructure today and still deploy very fastInternet have been an important infrastructure today and still deploy very fast Major characteristics of next generation Internet:Major characteristics of next generation Internet: –Large scale network: IPv6 address –End to end high performance –Secure and trustworthy network –QoS control network –Mobility There is not unify definition for next generation Internet but IPv6 should be an important part of NGIThere is not unify definition for next generation Internet but IPv6 should be an important part of NGI

6. Why is IPv6 needed? Much larger address spaceMuch larger address space –IPv6 Addresses: 3.4X10 38 Trustworthy network: real IP address accessTrustworthy network: real IP address access Improved routingImproved routing –Route aggregation reduces the size of routing tables –Simplified header reduces router processing loads Enhanced security and QoSEnhanced security and QoS –Mandatory IPsec support all fully IPv6 compliant devices Improved support for mobile IP and mobile computing devicesImproved support for mobile IP and mobile computing devices –IP is everywhere –Data, Voice, Audio and Video integration is a Reality –Regional Registries apply a strict allocation control
